The only way for you to know your partner’s results is if she agrees to share them with you. Some clinics will print results for their clients and if this is an option where she tests, you could ask to get a printout. Clinics may also allow partners to be present when results are given so you could also check into this but again it would only be with her consent.
You are right that she will have to ask specifically to be tested for STIs and HIV. Blood tests are usually used to check for syphilis and HIV but they cannot test for gonorrhea or Chlamydia, specific tests have to be done to check for those.
